According to the doubleterminal voltage traveling wave fault location

a new fault location algorithm based on the whole information of the transmission network is presented. When a fault occurs on one line

every substation records the arrival time of the first voltage traveling wave in the all transmission network

and the faulttolerant analysis and fusion processing are made by the master substation

then the synthesis fault location can be done by utilizing the useful time data. Thus the accuracy of fault location still can be guaranteed even though a locating device breaks down

starts failure or records the wrong time data. The results of simulation indicate that this algorithm has the strong fault tolerance and the high fault location accuracy.
